This UFO is unique in that it seems to be like a disk in nature but triangle shaped. This was an STS-106 mission, meaning the shuttle Atlantis visited the space station on Sept 8, 2000. The fact that it has a raised center would indicate is is made for transport of a species rather than being an alien drone. This was discovered by Streetcap1 of Youtube. He has some fantastic UFO evidence videos on his channel so if you like this kind of stuff, have a visits and give him a thumbs up for encouragement.
